Abstract
Techniques for assigning a network address to a host are based on authentication for a physical connection between the host and an intermediate device. One approach involves receiving first data at the intermediate device from an authentication and authorization server in response to a request for authentication for the physical connection. The first data indicates at least some of authentication and authorization information. A configuration request message from the host is also received at the intermediate device. The configuration request message is for discovering a logical network address for the host. A second message is generated based on the configuration request message and the first data. The second message is sent to a configuration server that provides the logical network address for the host. The configuration server is then able to provide the logical network address based on authorization and authentication information.
